A:Answer The A6000 is an APCS crop camera, so the 200mm to 600mm will be 300mm to 900mm so it will work well, keep in mind its heavy and will put alot of stress on the mount, so hold it up by the lens or use a tripod on the lens. Another option would be a 100mm to 400mm lens which would be 150mm to 600mm on your camera, good luck!
